Description

Bowdenzüge dienen bekanntlich zur Brems- und Gasbetätigung an Motorrädern.As is well known, Bowden cables are used to operate the brakes and accelerator on motorcycles.

Die als Schutzschlauch des Seilzuges dienende Umhüllung bestand bisher aus einer Flach- oder Runddrahtspirale. Um das Eindringen von Wasser, Schmutz usw. bei Verlegung des Bowdenzuges zu verhindern, was hauptsächlich an den Biegestellen der Spirale möglich war, wurde der, Schutzschlauch mit einem Garngespinst versehen und schließlich durch einen Lacküberzug vollkommen wasserdicht gemacht.The sheathing that served as a protective hose for the cable previously existed from a flat or round wire spiral. To prevent the ingress of water, dirt, etc. to prevent when laying the Bowden cable, mainly at the bending points the spiral was possible, the protective tube was provided with a thread spun and finally made completely waterproof with a varnish coating.

Der Erfindung liegt zunächst die Aufgabe zugrunde, die bisherige teure Umspinnung fortfallen zu lassen. Das geschieht erfindungsgemäß in der Weise, daß der neue Schutzschlauch aus einer inneren, zweckmäßig mit hoher Vorspannung gewickelten Runddrahtspirale, zwischen deren Windungen ein die Zwischenräume nach außen abdichtender Profildraht etwa in Form eines Hohlkehldreikants eingewickelt ist, besteht.The invention is initially based on the object of the previous expensive To drop the wrapping. This is done according to the invention in such a way that the new protective hose from an inner, suitably wound with high pretension Round wire spiral, between the turns of which one seals the gaps to the outside Profile wire is wrapped approximately in the form of a hollow triangle, consists.

Weitere Vorteile des neuen Schutzschlauches gegenüber der bisherigen Ausführung sind folgende: Erfahrungsgemäß scheuert sich ein an einem Motorrad verlegter Bowdenzug-Schutzschlauch nach längerer Zeit an den Stellen durch, an denen er mit anderen Maschinenteilen in Berührung kommt. Dabei reiben sich der wasserdichte Lacküberzug und ebenso die Umspinnung durch, so daß durch die eindringende Feuchtigkeit (Wasser, Schmutz usw.) der Schutzschlauch und später das Gas- oder Bremsseil anrosten und nach kurzer Zeit reißen. Durch den Fortfall des Lacküberzuges und der Umspinnung verringert sich der Außendurchmesser. Das wirkt sich naturgemäß auch auf die Anschlußstücke aus.Further advantages of the new protective hose compared to the previous one Execution are as follows: Experience has shown that someone laid on a motorcycle rubs off Bowden cable protective hose through at the points where it is with comes into contact with other machine parts. The waterproof lacquer coating rubs against each other and also the wrapping through, so that the penetrating moisture (water, Dirt etc.) the protective hose and later the gas or brake cable rust and tear after a short time. Due to the elimination of the lacquer coating and the wrapping the outside diameter decreases. Naturally, this also has an effect on the connecting pieces the end.

Durch seine größere Geschmeidigkeit ist der neue Schlauch im Hinblick auf seine Verlegung, also bei der Montage, bedeutend handlicher.Due to its greater suppleness, the new hose is in view on its laying, i.e. during assembly, much more manageable.

Die Gefahr des Durchdrückens des Lack- und Garnüberzuges während des Anklemmens der überwurfkappen ist bei der neuen Ausführung vollkommen ausgeschlossen. Gerade an diesen eben bezeichneten Stellen entstehen immer wieder bei dem alten Schlauch nach sehr kurzer Zeit Rostansätze, die unwiderruflich zur Zersetzung von Schutzschlauch und Seilzug führen.The risk of the lacquer and thread cover being pushed through during the Clamping of the cap is completely excluded with the new design. It is precisely at these points just mentioned that arise again and again with the old one After a very short period of time, the hose starts to rust, which leads to irreversible decomposition Guide the protective hose and cable.

Der neue Bowdenzug-Schutzschlauch ist infolge des Wegfallens der teueren Umflechtung um etwa 15% billiger als die zur Zeit auf dem Markt befindlichen handelsüblichen Bo«-detiziige. Außerdem ist er etwas leichter als diese.The new Bowden cable protective hose is due to the elimination of the expensive Braiding around 15% cheaper than the commercially available ones currently on the market Bo "- detective. It's also a little lighter than this.
